Wavelength of Radio Waves Emitted by a Resonant Circuit in a Radio Receiver

[waywardtigerlily]

A resonant circuit in a radio receiver is tuned to a certian station when the inductor has a value of 0.151mH and the capacitor has a value of 21.2pF. Calculate the frequency of the radio station.

Frequency is 2.81 MHz ( I got this one right)

B) what is the wavelength of the radiowaves emited by the radio station?
I was told to do this just take 1/f,but this gave me a wrong answer. Is there another way of going about it?

 

[MathStudent]

1\f is the period,

for wavelength you want to use the equation for all waves

$$v = f \lambda$$

where v is the speed of propagation of the wave

For this problem, $$v = c$$. All electromagnetic waves travel at the speed of light, so:

$$f = c/\lambda$$

 

[MathStudent]

Well there goes the chance of the OP doing any of the work for himself.

A lot of people don't know that, its not a question of doing work, its just a fact he needs.
